Brad is correct. Boxoffice Magazine of February 5, 1973, has an item saying: “Owner of the recently opened Malibu Cinema, a United General Theatres Franchise operation, is David O'Meara….” The house was still a single-screen theatre at least as late as early 1982, when the February issue of Boxoffice published a letter from David O'Meara in which he mentioned that the theater had 250 seats.
